Discuss your approach to completing this Hands-on Assignment. (1) What IP address did you choose for Router A’s LAN port? (2) What IP address did you choose for Router B’s WAN port? (3) Is Router A’s LAN port on the same subnet as Router B’s WAN port? What about the network topology suggests that it should or should not be? (4) In addition to the rows that are created automatically, is another routing table entry needed on Router A to enable it to forward packets to the LAN subnet on Router B? (5) Is a routing table entry needed on Router B to enable it to forward packets to the LAN subnet on Router A?
(1) What IP address did you choose for Router A’s LAN port?
The IP address I chose for Router A’s LAN port was 10.0.1.1/24 to connect the first 50 workstations.
(2) What IP address did you choose for Router B’s WAN port?
The IP address I chose for Router B’s WAN port was 10.0.3.2/30 for both routers to connect on a 10.0.3.x subnet based on my diagram.
(3) Is Router A’s LAN port on the same subnet as Router B’s WAN port? What about the network topology suggests that it should or should not be?
No, Router A’s LAN port and Router B’s WAN port would not be on the same subnet. While the switch connects the two routers, the purpose behind the two routers is different. Router A is not only meant to connect 50 workstations but also connect to the internet and Router B, while Router B is only meant to connect the other 50 workstations to Router A. Having them be on the different subnets is needed for communication to flow efficiently.
(4) In addition to the rows that are created automatically, is another routing table entry needed on Router A to enable it to forward packets to the LAN subnet on Router B?
Yes, a routing table entry is needed on router A to forward packets to the LAN subnet on Router B (10.0.2.0/24) via a static route. This would be via the IP address 10.0.3.2, which would connect to Router B via the WAN port into the LAN subnet.
(5) Is a routing table entry needed on Router B to enable it to forward packets to the LAN subnet on Router A?
Yes, an additional routing table entry is needed for Router B to forward packets to the LAN subnet on Router A (10.0.1.0/24) via another static route. This would be via the IP address 10.0.3.1, which would connect to Router A via the WAN port into the LAN subnet.
